This simplex sprocket with hub is identified by the code Simplex sprocket 5/8" Z43. It is a single-row power transmission component that mounts on a shaft and drives a 5/8" pitch roller chain. The integrated hub provides a mounting surface for keys or set screws to transmit torque.

The designation breaks down as follows: simplex indicates one row of teeth, 5/8" is the chain pitch, and Z43 is the tooth count. The sprocket is made of SAE 1045 steel. The hub is the raised central section that contacts the shaft and allows fastening with a key, set screw, or interference fit.

This sprocket is commonly found in chain drives on conveyors, packaging equipment, production lines, agricultural machinery, and elevators. A 5/8" pitch suits roller chains for moderate loads and medium speeds. With 43 teeth, it is used where the drive requires speed reduction or increased output torque, depending on the arrangement.

When selecting or replacing the sprocket, confirm the chain pitch (5/8"), the number of teeth (43), and the shaft diameter. The hub bore must match the shaft and the chosen fastening method. Check alignment between sprocket and chain to avoid premature wear. SAE 1045 steel can be hardened and tempered, depending on the final treatment.

To request an equivalent or a different size in the same 5/8" pitch series, provide the pitch, tooth count, and required shaft diameter.
